XRA1202IG16-F

Overview

The XRA1202IG16-F is an 8-bit I/O expander manufactured by MaxLinear, designed for low-voltage applications. It operates within a supply voltage range of 1.65 V to 3.6 V and supports I2C and SMBus interfaces with clock frequencies up to 400 kHz. The device features open-drain outputs capable of sourcing or sinking up to 160 mA, with a maximum power dissipation of 200 mW. It includes interrupt output functionality and functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in a 16-pin TSSOP package suitable for surface-mount assembly.

Feature Summary

• Supports standard I2C and SMBus communication protocols for system integration
• Provides configurable 8-bit general-purpose input/output expansion
• Includes dedicated interrupt output pin for efficient event handling
• Operates with low voltage requirements suitable for portable electronics

Applications

• Portable consumer electronics requiring GPIO expansion
• Industrial control systems utilizing SMBus interfaces
• Embedded systems needing low-power I/O management

Procurement Notes

Verify the current lifecycle status as the XRA1202 series may be obsolete or restricted. Confirm availability through authorized distributors or secondary market suppliers. Ensure compliance with RoHS directives and check for moisture sensitivity levels prior to soldering. Validate that the specific suffix matches the required package and tape/reel specifications for your manufacturing process.

Selection Notes

Select this component when an 8-bit I/O expander with I2C/SMBus interface is required. Compare against similar models like the XRA1200 or XRA1201 if different bit widths are needed. Consider the TSSOP-16 package constraints and ensure the operating voltage aligns with the 1.65 V to 3.6 V range. Verify interrupt line compatibility with the host microcontroller.

Part Context

This part belongs to the XRA1200 series of I/O expanders from MaxLinear (formerly Exar). It shares functional similarities with other members like the XRA1200IG16-F but offers specific configuration options. The series is designed for cost-effective GPIO expansion in space-constrained designs. Note that MaxLinear has undergone corporate changes affecting product lines.

Replacement Considerations

Check for direct replacements such as the XRA1200IG16-F or XRA1201 series if pin-compatible alternatives are needed. Cross-reference with Texas Instruments TCA9554A for functional equivalents. Verify pinout compatibility before substitution.
